The chassis number (series number or VIN number) on the website often corresponds to the last characters among the 17th of the alphanumeric code. Before 2004, the last 8 characters were written on "series number type" zone of the registration certificate. From then, it is completely written on E zone "Vehicule Identification Number". In general, it is also engraved on the engine compartment, on the front passenger doorstep and in the boot.
